Last weekend I talked to my wife about business travel and how business travel might not take place in the future anymore, b/c oil prices are through the roof. I remember saying that business travel is often kind of unnecessary anyways and flying for vacation or in an emergency should probably be the only time people should be allowed to fly.
Today I was surprised that I wasn't even that far off. Cisco presented a new holographic video conference, which really makes business travel obsolete.

It seems that Cisco finally helps us to get rid of all these awful unpersonal WebEx / Gotomeeting web conferences.
